Linux will not start - probably a mounting problem.


I am newbie with Linux.

I did a terrible mistake and I hope it can be fixed easily without losing any data.

I installed FC5 and worked with it for few months.

I have the last kernel 2.6.18

I have an IDE HD (hdc1)

Few days ago I've installed a new SATA HD (I think marked as hds1).
I've created a new partition, a new logical volume and mount it. I set the mounting point to "/" ;(

The day after when I try to open the computer, the Linux boot halt at the middle with some errors "...FC5 cannot touch /var/lock/subsys/kudzu Read-only".

I tried to use the DVD in order to "upgrade" the OS. At some point I've got that its cannot find the "/" and I might have a problem with the stable file.

I am almost sure that I need to remove the new mounting point in order to make it work.

Can someone help me with that. I have no idea what to do.
Please write the required steps in detail.

Many thanks,
Shay

Just try it out with a live cd and edit your fstab. This might help you.

I used the installation DVD in order to get to rescue mode.
I could not find the fstab file at /etc/fstab

Mount the partition where you have your linux installed. chroot to the partition and then edit the fstab.

After you have booted with the help of the live, open a terminal and go to the root prompt. Do a fdisk -l, which will list all the partitions. Mount the partitions using the mount command. chroot to the patition where you have your / partition. As an example,

Code:
root@foobar:~$ fdisk -l

Disk /dev/hda: 255 heads, 63 sectors, 4870 cylinders
Units = cylinders of 16065 * 512 bytes

   Device Boot    Start       End    Blocks   Id  System
/dev/hda1   *         1      4839  38869236   83  Linux
/dev/hda2          4840      4870    249007+   5  Extended
/dev/hda5          4840      4870    248976   82  Linux swap

root@foobar:~# mkdir /tmp/hda1
root@foobar:~# mount -t ext3 /dev/hda1 /tmp/hda1
root@foobar:~# cd /tmp/hda1
root@foobar:~# chroot .
root@tty[/]# nano etc/fstab
I hope that helps you.

I followed your instructions.
However, when I type chroot I get
Quote:
cannot run command '/bin/bash':no such file or directory.
What I am doing wrong?

copy the output of your fdisk -l here so we can see what you have got

then if you can see /etc/fstab when you have mounted the drive copy the output of that to here

(use cat /etc/fstab to view the contents

BTW, you don't see the SATA HD because the I have a mother board chip that required kernel 2.6.18 to support it.
The live CD has an older kernel version.
In any case the OS was installed on the first HD (IDE)
